Laravel:ArgumentCountError: Too few arguments to function App\Mail

I failed to make the email queue. Not sure what is wrong as I keep getting the error.

‘ArgumentCountError: Too few arguments to function
App\Mail\TransactionSuccess::__construct()’.

What I’m trying to do is to pass the $trx variable when sending emails.

TestController.php

class TestController extends Controller
{
    public function sendtrx(){
        $trx = Transaction::find('123');

        dispatch(new TrxEmailJob($trx));
    }
}

Jobs/TrxEmailJob.php

class TrxEmailJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    protected $trx;

    public function __construct(Transaction $trx)
    {
        $this->trx = $trx;
        // dd( $this->trx);
    }

    public function handle()
    {
        Mail::to($this->trx['user_email'])->send(new TransactionSuccess());
    }
}

Mail/TransactionSuccess.php

class TransactionSuccess extends Mailable
{
    use Queueable, SerializesModels;

    public $trx;

    public function __construct(Transaction $trx)
    {
        $this->trx = $trx;
    }

    public function build()
    {
        return $this->view('Hey Test')
            ->markdown('emails.transactionsuccess');
    }
}

I expect to send an email with details from $trx; however, the job fails based on the table.

>Solution :

Update the handle() method to the following.

public function handle()
{
    Mail::to($this->trx['user_email'])
        ->send(new TransactionSuccess($this->trx));
}
